On 13 February 2017, the eldest son of Kim Jong Il and half-brother of Kim Jong Un, Kim Jong-nam, was attacked with the nerve agent VX at Kuala Lumpur International Airport in Malaysia. He had been exiled from North Korea in 2003 and had been living abroad.
Following his visit to the resort island Langkawi, Kim Jong-nam had arrived at terminal 2 sometime before 9:00 a.m. to take a 10:50 a.m. AirAsia flight to Macau. At approximately 9:00 a.m., two women ambushed Kim Jong-nam with the VX nerve agent. He died about 15 to 20 minutes later.
The women were identified as Siti Aisyah from Indonesia and Đoàn Thị Hương from Vietnam. Both were charged with the murder of Kim Jong-nam. The charges were dropped, although Hương pled guilty to "voluntarily causing hurt by dangerous weapons or means" and received a sentence of three years and four months. Four North Korean suspects left the airport shortly after the assassination and reached Pyongyang without being arrested. Other North Koreans were arrested but were released without charge.
It is widely believed that Kim Jong-nam was murdered on the orders of Kim Jong Un.
